- MPM1D, MFM1P, MFM2P
- determine values of a linear relation by using a table of values, by using the equation of the relation, and by interpolating or extrapolating from the graph of the relation
- determine other representations of a linear relation, given one representation
- describe the meaning of the slope and y-intercept for a linear relation arising from a realistic situation
- determine the equation of a line from information about the line

- Tape/stick tack
- Beach Ball (optional)
- Whiteboard markers (optional)

- Each group of 3 students gets 1 representation of a linear relationship - either a story, equation, table or graph. Students will complete a scavenger hunt by roaming around the room to find the other 3 representations of their linear relationship. The other three cards in each set are randomly distributed around the class before hand.
- Once all four cards are together, each group must fill in missing information on the graph (title and axes labels) and in the table (column titles and table values - CAUTION: yellow rows are out of step in the pattern). Teacher can check missing information quickly using reference card.
- Each group will tape their equation in the middle of their desks.
- Each group will now tape their story to the beach ball. Students will throw the ball and each group will select a card (not their own). That group must now find the equation of the new story they got off the beach ball. One member will then circulate to check if the equation is correct with the original group for their new story and return it to that group.
- Repeat step 4 with the tables.
- Repeat step 4 with the graphs.
- Each group should now have the original 4 representations of their linear relationship. Students will now answer 5 questions related to their relationship found on the Question Cards.

**Other possible uses**

- give a story or equation to each student and have them find their partner
- give each group of 3 an equation and have them describe several situations that could be modelled by the given linear equation.
- give students a card and have them identify as a direct or partial variation
- give a student a table or graph - have them find the rate and explain its meaning

- Note that if you print these out on card stock and laminate them, students can use whiteboard markers or whiteboard crayons to do their work on them and can be reused.
